Hi Stick You just insert the advanced regulator into this lead/wire,f you have a 80 amp alternator you would need a 16mm cross section cable or 25mm if going further away from alt/ batt, alternators do get hot the controller has a wire to alternator and one to batt only 5 amp) to monitor the temp so easy to fit. but marine ones not only corrosion proof but larger fan blades to help with cooling, as against auto derived ones that rely on a air flow from/ through front of car/lorry.I have a engine room extractor fan that comes on automatically with ignition then runs for 5 minutes after engine shut down this has lowered the engine room temp dramatically. Those starter coils you spoke of are for break downs as they are lighter to carry to stopped engine not suitable for running fridges etc.I am surprised that you manage with just two batteries assuming they are 110 amh, you must be very disciplined,i am afraid that we cant do with out tv/dvd and electric blanket ,Hope you can get on mains for winter,John

Thanks once again. I'm not sure how I manage on the two batteries either and up till Aug this year it was only the one battery! Both 110ah leisure traction batteries and my cable cross sectional areas are bigger than ( what you advised) that ! My starter cable and all earthing cables are military spec grounding leads for aeroplanes so CMA is the width of your little finger! Resistance of 0.1ohm. My terminals are also military spec.... There were some perks to being in for so long! Speaker cables and low current 12v is black n tan the low resistance cable I used for triggering electric detonators..  Brilliant stuff and we had to throw quite a lot away as if it had been in a " blow" you had to snip the possibly damaged 5-10 feet of the end! Shame I'm out of it now and last bonding lead went on my welding set! Use of battery power is very regimented but fortunately I'm on my own so as one of my old instructors once said " no such thing as cold, boy! Just improperly dressed!" If I want tv on at night I don't use power all day, night is one LED light one candle.... If sun out I can listen to stereo all day if no sun I listen to rechargeable blue tooth speaker and phone recharging next day as I do get a bit of the magic leccy even on dull days... It's fun really! I've lived worse! I do have an electric blanket but as I lay on bed reading in evening or watching DVDs I'm warming it up to get in later and if you don't have an eiderdown duvet I can definatly recommend one! Thin and not heavy 12 tog is sooooooo toasty! I even let the fire go out most nights as I like to sleep with my head in the cold! Last night I had two portholes open and it was lovely!! But I am odd! I secretly think my batteries and charging circuit are bigger on the inside than the outside and it really is magic.... If you have a look on the other web site there are some pics of inside my front cabin....the bit of the hull with the portholes in.... And she looks a lot bigger inside than she looks outside! My boat is my Tardis and my home and I love her.... My batteries are baby Tardis 's and it really is MAGIC!

Evening All.

Looking for some advice if you would be kind enough.
We are thinking of installing some solar panels.
The area available is 1.1 x 1.0m
and would like as higher wattage as possible around 200w if possible.
So have the following questions.
Is there any particular type of panel that is considered better than any other, was thinking of semi flexible ?.  
Does anyone know of panels that are made to different sizes to the standard as I can't fit in 2x100w panels in the space I have.
The next problem is that I keep an all over cover on the boat all of the time so I would need another panel to fix to the mooring to keep the batteries charged what size would be appropriate for that?
I have seen some on Amazon but not sure of quality. I have added a link what do you think?

I have been to a well regarded yard on the Northern side for a quote for the job, but unfortunately after 2 weeks and an e-mail to prompt them I've had no response so that has put me off before we start!

Any thoughts would be most appreciated.

Hi Spiderman The flexible ones aren't as good as rigid ones, poly ones are better than mono, you dont say how many batteries you have!  i have four 110amp and have a 150w panel with a regulator that keeps batteries fully charged up when not on boat if you google Bimble they have second hand ones, or Photoelectronics have a excellent site.Cris from SOLAR ENERGY in lowestoft opposite fish market at the harbour, tel 515532 0r 07787564308 is very helpful and will come to your boat and fit solar panels for you. hope this helps if not contact me.John

Thanks very much for that I'll check them out.
I have 2x110 domestic batteries plus the starter one.
Would like to be pretty much self sufficient in power  while on the boat if possible.
Cheers!

Hi Spiderman It's not easy to be self sufficient, first how long do your batteries last? say one night plus one day+ 2x 110 amps +220 less 50%= 110 say 100 amps divide hours of sun 8= 12 amps = 150 watt panel??? BUT if moored in shade panels not angled to sun or a dull day   so only 4 amps produced so you need 3x150w = 500w panel, you don't need to charge starter battery BUT if moored and not used it will need charging some solar regulators have two outlets ie domestic and starter, or you can use a battery-battery charger, i use this because if on shore power it still charges starter battery from domestic battery and if on solar it still charges starter batt,!more money of course but !!!. This is rule of thumb workings but you can see the problems. OR OVERKILL 5X250 panels 1,250w= 140 amps or 50 amps dull day charge battery in 2 hrs. but money money and space on roof. the one good thing is there is no running costs unlike running engine or running a generator to produce power, the same with shore power although this is the cheapest when available but you might need a long power cable.

Go see Alan at Sabina, he fitted a panel for us last autumn and it keeps out 2 x 110 batteries well charged for daily use. We don't  cruise far on weekends but have plenty of power.

What size panel did you have?
Like you we don't like to cruise too much, it would be nice not to have to keep thinking about the state of the batteries all the time.
I'm fixated about discharging them too much.

spiderman, every situation is different, so a 100% answer is difficult. May I suggest you first of all fit a battery monitor, so you can keep a close eye on the state of your batteries. I have a NASA BM-1 (other makes are available), which was simple to install and monitors my two 110 amph leisure batteries fully, and the voltage of my starter battery. It saves me fretting about running the leisure batteries down too low. A starter battery doesn't need so much cossetting, as it is usually in a state of full charge all the time.

Self-sufficient? Probably achievable during the summer months, but very difficult if you use the boat in the winter. You have a very limited amount of space for a panel and it is unlikely there will be enought sunlight to keep your leisure batteries charged on solar power alone.

Is there any particular reason you're thinking of a flexible panel? They are more expensive. You can get more bang for your bucks if you get a rigid panel.

I have a 218w rigid panel (similar to those used for domestic installations). This will run (on a daily basis) an Isotherm fridge, lighting and tv. On sunny days, in mid-summer, the batteries are charged up again by around 10am, if not before. On dull days, or when the nights are drawing in, I might have to go for a cruise for a couple of hours.

To keep the starter battery topped up during the winter, I hang a small (30w) panel in one of the window. A smaller panel would probably cope, but this is the panel I used for the leisure batteries, before I fitted the bigger one.
